ATTACHMENT FOR PUMPS.

Application filed June 2, 191.3.

Y '0 all whom it may concern:

Be it known that 1, WILLIAM ll. Goss, a citizen of the United States, residing at lrlammonton, in the county of Yuba, State of California, have invented certain new and useful Improvements in Attachments for Pumps; and I do declare the following to be a clear, full, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in pump apparatus used for raising water from wells or similar places the object of the invention being to produce an attachment for pumps which will permit a suction pump to be operated to lift water from a greater depth from that which can be done by the ordinary type of pump now commonly used. As is a well known fact any ordinary suction pump can only lift water approximately from thirty to thirty-three feet and it is the aim of my invention to provide a means whereby when the approximate thirty feet is lifted the load may be relieved for a period and then when the lifted weight is reduced the load can again be taken up, thus permitting the pump to continue to operate uninterruptedly irrespective of the depth from which it may be lifting the water.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed.

These objects, I accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusal of the following specification and claims On the drawings, similar characters of reference indicate corresponding parts in the several views.

Figure l is a sectional view of a well and pump showing my improved attachment connected therewith, and showing 110w the attachment floats on the water level and rises and falls with such water level. Fig. 2 is a sectional view taken on a line X--X of Fig. 1. Fig. 3 is a detached end view of an air inlet valve. Fig. l is a plan view of a valve controlling piston.

Referring now more particularly to the characters of reference on the drawings, the

Specification of Letters Patent.

Serial No. 771,169.

numeral 1 designates the well in which 2 designates the water level. The numeral 3 designates the pipe projecting into the well and provided with the pump l.

My improved attachment consists of a float 5 adapted to be disposed on the top level of the water 2. Mounted on the float 5 is a cylinder 0, the same being closed at one end and having a hole 7 in the other end, there being a. valve 8 normally closing said hole. Said valve 8 is provided with a stem 9 having a peforated piston 10 at its other end there being a spring 11 disposed in the cylinder ('3 and normally engaging the piston 10 to hold the valve 8 closed over the hole 7. The tension of the spring 11 is maintained and fixed by means of a threaded member 12 screw mounted in the end of the cylinder (3 and engaging said spring ll and provided with an adjustment thumb screw 13 connected therewith by a stem H projecting through the closed end of the cylinder 6. As will be seen, by the movement of the member 13 the member 12 may be ad vanced against or retracted away from the spring 11 which will increase or decrease its tension,

Colnmunicating with the cylinder 6 at right angles thereto and between the valve 8 and the piston 10 is a pipe 15, such pipe being connected by a flexible hose member 16 with the pipe 3 by means of a T-member 17, such flexible hose permitting the device to rise and fall with the water level whereby it will always be open to the atmosphere although of course the only time the device would be called into operation would be when the water level was such that the T- member 17 was out above the water level With the operation of the pump l, which may be a hand or power pump, the suction of the pump at will lift the approximate distance heretofore noted which is its limit. The spring 11 is fixed at such a tension as to resist approximately the pressure occasioned by the suction caused by the lifting of that quantity of water. Then, therefore, when amount of water allowed by the practical suction limit has been lifted in the pipe 3, this has created a suction through the members 16 and 15 against the valve 8 of a proportionate amount, but the spring 11 resists this suction and holds the hole 7 closed by said valve 8. When however, the practical suction limit has been reached and the pump continues to work, this increases the suction against the valve 8 and causes it to overcome the resistance of the spring 11 and to be lifted away from the hole 7 and air is then taken through the 5 hole 7 and through small slits 8 in the sides of the valve 8 and this air then passes through the members 15 and 16 into the pipe 3 relieving the load, which release is continued until the amount of water allowed 10 by the practical suction limit is lifted to the head of the pump and a part of it dis charged and then since this relieves the pressure against the spring 11 it will close the valve 8 and water will then be lifted 15 again into the pipe 3 and this operation will continue as long as the pump is op erated.

Instead of the float mechanism for holding the air inlet mechanism, I may of course provide the air inlet mechanism at any convenient point, such as the top surface of the ground or at any point desired by connecting the same with a pipe to the lower end of the well pipe. Also while I have provided a specific form of valve mecha: nism for the air inlet structure, still any other structure found desirable may be used, such as placing the air inlet slots in the side of the cylinder instead of the valve and also in forming the operating pistons of rubber or any other similar material.

From the foregoing description it will be readily seen that I have produced such a de vice as substantially fulfils the objects of the invention as set forth herein.

\Vhile this specification sets forth in de tail the present and preferred construction of the device, still in practice, such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is l. A device of the character described comprising the combination with a pipe and a pump, of a cylinder open at one end, a valve forming a normal closure for said open end, a stem on said valve, a spring pressed piston on the other end of said stem, and a conduit leading from said cylinder between said valve and said piston and communicating with said pipe, as described.

2. A device of the character described comprising the combination with a pipe and a pump, of a. cylinder open at one end, a valve forming a normal closure for said opening of said cylinder, a spring pressed piston connected with said valve, means for fixing the tension of said spring and a conduit leading from said cylinder between said valve and said piston and connected with said pipe, as described.

In testimony whereof I afliX my signature in presence of two witnesses.
